Teenager on mission to promote sign language enlists celebrity help
Video report from ITV News correspondent Rupert Evelyn
A teenager from Bridgend in South Wales is on a mission to get as many people as possible to learn sign language.
16-year-old Isabella taught herself to sign so she could communicate with her brother Lucas, who has Down's Syndrome.
And to highlight World Down's Syndrome Day on Sunday, Isabella persuaded a group of celebrities to take part in a very special video.
